Social and Environmental Report
The District Cooling System (DCS) is considered an energy-efficient way to supply cooling for multiple buildings within a local area. In general, a DCS can save 20% to 35% of electricity consumption as compared with conventional central air-conditioning systems separately installed in individual buildings, thus reducing carbon emissions. For the EMSD Headquarters Building, the Kai Tak DCS came into operation from 2013. The total estimated electricity saving in the year 2021/22 amounted to about 138 million kWh, which is equivalent to reducing 96500 tonnes of carbon emissions per annum.
EMSD’s DCS project moved a step further with the support of the then Environment Bureau to provide additional cooling capacity of 178 megawatt of refrigeration for the Kai Tak Development, bolstering the cooling capacity of the existing North and South DCS Plants. Upon full utilisation, the additional DCS project is estimated to save up to 53 million kWh of electricity a year, representing an annual reduction of about 37000 tonnes of carbon emissions.
